Not support integer setter in JDBC PreparedStatement

[chenjienn]

When i run the code below, it works

String sql = "match (x:meta_table {table_id: ?}),(y:meta_table),\n" +
                "path=allshortestpaths((x)-[:meta_table_lineage*1..1]->(y))\n" +
                "return path";
 return jdbcTemplate.query(sql, ps -> {
            ps.setString(1, tableLineageInfo.getTableId());
        }, new ResultExtractor());

but when i run the code below, it doesn't work and throw the exception

String sql = "match (x:meta_table {table_id: ?}),(y:meta_table),\n" +
                "path=allshortestpaths((x)-[:meta_table_lineage*1..?]->(y))\n" +
                "return path";
 return jdbcTemplate.query(sql, ps -> {
            ps.setString(1, tableLineageInfo.getTableId());
            ps.setInt(2, tableLineageInfo.getLayerNum());
        }, new ResultExtractor());
